A simple example where information-theoretic entropy is used where there is no physical representation: Video codecs. I'm guessing you've heard of mpeg and h.264 encoding. Which one encodes a movie better? One way of answering this quest

Not, and moreover, you've mixed apples and oranges. A system's entropy in statisical mechanics is k log W, where k is Boltzmann's constant and W is the number of microstates. The microstate is a configuration of, say, electrons in energy l

No. The photon population is not in thermal equilibrium. (They are concentrated at one energy, rather than obeying the Bose-Einstein distribution vs energy.) More generally: A negative absolute temperature is possible only when the distr

The usual explanation of such things: T is not so important as 1/T. So negative abs temp is achieved by going through +infinity temp and coming back via -infinity temp. Note that this is only allowed in systems which have states that are

Completely agree. And the fact that D&B gets to sell the info? Inexcusable. This is a service that is simply begging for some competition, and I'm waiting for a startup entrant.

That's OK, there are dihonest people everywhere. The only correct response to such a situation is: "I will tell everyone I know about your tactics, and go with the dealer that was shooting straight." Then execute on exactly that plan.

The value of Myers-Briggs has nothing to do with its accuracy: Good tests start by telling you that humans are too complex for a 4 axes characterization. The value of MB is teaching interaction. Many people, esp those in tech fields, h

Remember when you needed to pay for email storage? Competition drove that price to zero as companies used it as a loss leader for other revenue streams (eg, advertising). I suspect a similar outcome. The question is when, of course.

We really need to subject congressmen and congresswomen to these searches. They should not be exempt. My guess is that is the only way the problem gets taken care of quickly.
